This feature has nothing to do with OpenSIPS which is just a proxy (and more 
things) and it only routes requests.

Of course, you can implement it with OpenSIPS:
- Suppose the complete number to dial is 123456.
- GW sends 1 to OpenSIPS and it replies 484 "Address Incomplete"
- GW sends 12 and OpenSIPS replies 484.
- GW sends 123 and OpenSIPS replies 484.
- GW sends 1234 and OpenSIPS replies 484.
- GW sends 12345 and OpenSIPS replies 484.
- GW sends 123456 and OpenSIPS routes the call.
